В случае многоосного сжатия бетона происходит увеличение его прочностных показателей, что может быть выгодно использовано при расчетах и проектировании конструкций. В связи с недостаточной проработкой вопроса в современной научно-технической и нормативной литературе был подготовлен эксперимент по изучению особенностей поведения современных, в том числе высокопрочных, бетонов в условиях многоосного напряженного состояния. Были исследованы образцы с внешним листовым армированием. Оценка особенности работы бетона при сложном многоосном напряженном состоянии выполнена на основе результатов экспериментальных исследований и анализа существующего мирового опыта. Представлено описание исследуемых моделей, приведены особенности использованных при изготовлении моделей материалов и их характеристики. Приведены данные об экспериментальном оборудовании, схеме испытания и нагружения конструкций. Представлены общие виды и характер разрушения, графические результаты испытаний. Выполнено сравнение теоретических и экспериментальных данных.</p></abstract><trans-abstract xml:lang="en"><p>Modern structures of buildings made of concrete, reinforced concrete and composite steel and concrete are in a complex stress state, which leads to a change in their strength characteristics. In the case of multiaxial compression of concrete, its strength indicators increase, which can be advantageously used in calculations and design of structures. Due to the insufficient study of the issue in modern scientific, technical and regulatory literature, an experiment was conducted to study the behavior of modern, including high performance concrete in a complex multiaxial stress state. Models with steel-plate reinforcement were investigated. The assessment of the behavior of concrete in a complex multiaxial stress state is based on the results of experimental research and analysis of existing international experience. The description of the studied models is presented, the features of the materials used in the manufacture of models and their characteristics are given. Data on experimental equipment, the scheme of testing and loading structures are presented. The general types and nature of destruction, graphical test results are presented. A comparison of theoretical and experimental data is performed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бетон</kwd><kwd>сталь</kwd><kwd>железобетон</kwd><kwd>сталежелезобетонная конструкция</kwd><kwd>листовое армирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>concrete</kwd><kwd>steel</kwd><kwd>reinforced concrete</kwd><kwd>composite steel and concrete structure</kwd><kwd>steel-plate reinforcement</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">СП 63.13330.2018.
